One of Rogers' most-viewed posts was of him signing the Boyz II Men ballad "On Bended Knee," which won him an invite from the group to perform with them in Las Vegas earlier this year.

"Just a genuinely nice person and a really good singer! Gone too young and gone too soon. It hurts to know that the world will never have a chance to witness what his impact on the world could have been as a Doctor and even on the music world," the group said in an Instagram post.

A spokesperson for "America's Got Talent" told TODAY, "We are deeply saddened by the tragic passing of Dr. Brandon Rogers, who graced the 'America’s Got Talent' stage as a contestant. Our thoughts are with his family."
